Genbank Search software

Hello ALL!
I would like some information on PC based software that is available for
searching the Genbank database on CD-ROM. We have been using the IBI
Pustel program but it apparently is not compatible with the Genbank data
on CD-ROM. The commercial software we have found so far has been
prohibitively expensive. Any suggestions would be greately appreciated.
